Internal layer rope 1 have the center of being configured at internal layer cord fibers core 3, be immediately twisted the many inner-electron ropes 4 in the periphery of internal layer cord fibers core 3 and be covered in the resinous internal layer rope nappe 5 of periphery.
Internal layer cord fibers core 3 uses the sth. made by twisting core of the syntheticfibres be such as made up of polypropylene or polyethylene.Further, internal layer cord fibers core 3 by by 3 mutual twisteds of core strand and from periphery pressurization and form.Each bar core strand is formed by by many lines of syntheticfibres harness.In addition, internal layer cord fibers core 3 is impregnated with rope grease.
Many steel single line twisteds form by each bar inner-electron rope 4.More particularly, each bar inner-electron rope 4 has the inner-electron wire rope core single line 6 at the center of being configured at and is twisted together in the double-layer structural of many (be 6 at this) outer single lines 7 of inner-electron rope of periphery of inner-electron wire rope core single line 6.The diameter of inner-electron wire rope core single line 6 is identical with the diameter of the outer single line 7 of inner-electron rope.
The diameter of inner-electron rope 4 is less than the diameter of outer straton rope 2.At this, the diameter of inner-electron rope 4 is less than 1/3 of the diameter of outer straton rope 2.Further, the number of inner-electron rope 4 is more than the number of outer straton rope 2.At this, relative to 8 outer straton ropes 2, use 12 inner-electron ropes 4.
The material of internal layer rope nappe 5 adopts such as polyethylene or polypropylene etc. to have the resin of hardness to a certain degree.Internal layer rope nappe 5 respectively between adjacent outer straton rope 2, between adjacent inner-electron rope 4 and between outer straton rope 2 and inner-electron rope 4.
The outer straton rope 2 of each bar be have the center of being configured at outer straton rope fibre core 8, be twisted together in outer straton rope fibre core 8 periphery many outer straton ropes in the middle of single lines 9 and be twisted together in the three-layer structure of many outer straton ropes skin single lines 10 of periphery of layer of single line 9 in the middle of outer straton rope.The number of single line 9 identical with the number of outer straton rope skin single line 10 (be respectively 12 at this) in the middle of outer straton rope.
Outer straton rope fibre core 8 adopts the sth. made by twisting core of the syntheticfibres be such as made up of polypropylene or polyethylene.Further, outer straton rope fibre core 8 is formed by by many lines of syntheticfibres harness.In addition, outer straton rope fibre core 8 is impregnated with rope grease.
In the middle of outer straton rope, the diameter of single line 9 is less than the diameter of the outer single line 10 of outer straton rope.The diameter of outer straton rope fibre core 8 is greater than the diameter of the outer single line 10 of outer straton rope.Further, the diameter of single line 6,7 that inner-electron rope 4 comprises is less than the diameter of any single line 9,10 that outer straton rope 2 comprises.
In such Riata for elevator 28, internal layer rope nappe 5 is set in the periphery of internal layer rope 1, and straton rope 2 arranges outer straton rope fibre core 8 outside, thus rope grease can be made to impregnated in the inboard portion of internal layer rope nappe 5, and rope grease can be made also to impregnated in outer straton rope fibre core 8.Therefore, at the use initial stage, the rope grease of outer straton rope fibre core 8 can be supplied to the single line 9,10 of outer straton rope 2, due to all the year round use and internal layer rope nappe 5 produce be full of cracks after, by be full of cracks rope grease is supplied to the single line 9,10 of outer straton rope 2, can from the use initial stage the lubricity of long term maintenance rope grease.
Further, at the center configuration internal layer cord fibers core 3 of internal layer rope 1, enough rope greases thus can be made to impregnated in the inner side of internal layer rope nappe 5.
In addition, the diameter that the diameter being configured at the inner-electron rope 4 of the periphery of internal layer cord fibers core 3 compares outer straton rope 2 is enough little, thus fully can guarantee the sectional area of internal layer cord fibers core 3, fully can guarantee the content of rope grease.
In addition; the many inner-electron ropes 4 than outer straton rope more than 2 are configured with in the periphery of internal layer cord fibers core 3; thus inner-electron rope 4 can being utilized to protect internal layer cord fibers core 3 when forming internal layer rope nappe 5, preventing the fibers melt of internal layer cord fibers core 3 and rupturing.
And, when twisted inner-electron rope 4, internal layer cord fibers core 3 is fastened, thus the constructional gap in internal layer cord fibers core 3 significantly reduces, when can prevent from using all the year round, internal layer rope 1 is out of shape diameter that (clinging) cause and reduces and the increase of contact between the outer straton rope 2 that causes thus, can prevent the single line of outer straton rope 2 from wearing and tearing.Therefore, it is possible to realize the more long lifetime of Riata for elevator 28.
In addition, internal layer cord fibers core 3 is configured at center, and steel that thus there is not twisted of not restricting with other son is restricted.That is, whole sub 2,4 certain and other sub 2,4 twisteds of restricting of restricting.Therefore, not easily produce the broken string of single line 6,7,9,10 and relax, the long lifetime of rope entirety can be realized.
In addition, by having the polypropylene or polyethylene etc. of self lubricity as the materials'use of internal layer rope nappe 5, when rope grease in internal layer cord fibers core 3 is exhausted owing to using all the year round, the lubrication between internal layer rope 1 and outer straton rope 2 also can be suppressed to worsen and single line is worn and torn increase the intensity caused to decline.
In addition, the sectional area of inner-electron rope 4 is less, and straton rope 2 is provided with outer straton rope fibre core 8 outside, and thus the unit mass of rope can increase necessarily, such as, can replace the Riata for elevator of existing lift appliance and directly use.
Such as, as shown in Figure 1, by internal layer rope 1 being set to the structure of 12 (son rope number) × 7 (single line numbers), the number of outer straton rope 2 is set to 8, the single line number of outer for each bar straton rope 2 is set to 24, also, compared with being the situation of internal layer cord fibers core 3 with the part of hypothesis inner-electron rope 4, the unit mass that inner-electron rope 4 can be caused increases suppression within 5%.
At this, when producing small be full of cracks owing to using all the year round at internal layer rope nappe 5, by be full of cracks, rope grease is supplied to outer straton rope 2.On the other hand, when the thickness of internal layer rope nappe 5 is blocked up, likely can not supply rope grease, and the sectional area of internal layer cord fibers core 3 reduces, the pickup of rope grease also reduces.
In order to prevent inner-electron rope 4 from contacting with outer the direct of straton rope 2, need internal layer rope nappe 5 is fallen between.But, in order to the thickness preventing the internal layer rope nappe 5 directly required for contact is about 1% of rope diameter.Therefore, consider the manufacturing errors during construction covering construction and outer straton rope 2, preferably the thickness of the internal layer rope nappe 5 between inner-electron rope 4 and outer straton rope 2 is set to less than more than 1% 2% of the diameter of Riata for elevator 28 entirety.
In addition, by using the internal layer cord fibers core 3 of syntheticfibres, compared with the natural fibers such as the sisal hemp of the core rope materials'use usually used as Riata for elevator, the gap in internal layer cord fibers core 3 can be reduced, the distortion (clinging) when further suppression uses all the year round.And the characteristic can not decomposing this material self according to adding water suppresses the corrosion under high humidity environment.Therefore, it is possible to prevent the internal injury likely produced between straton rope 2 or between outer straton rope 2 and internal layer rope 1 outside more reliably.
In addition, the intensity of Riata for elevator 28 is designed to substantially removing inner-electron rope 4 and also can supports loading.And, by being set to that the diameter of the single line 6,7 that inner-electron rope 4 comprises is less than the diameter of any single line 9,10 that outer straton rope 2 comprises, or be set to the pulling strengrth of any single line 9,10 that the pulling strengrth of the single line 6,7 that inner-electron rope 4 comprises comprises higher than outer straton rope 2, inner-electron rope 4 broken string more Zao than outer straton rope 2 can be prevented, broken string produces from outer straton rope 2, easily judges the deterioration of Riata for elevator 28 according to outward appearance.
